Description

I am attempting to implement AmgX's algebraic multigrid preconditioner in Petsc. When I include the following optional database keys

-pc_amgx_amg_method CLASSICAL

I encounter the following error

Caught amgx exception: SelectorFactory 'PMIS' has not been registered

I have attached the outlog, errlog and toolkits files for your reference. Does anyone know what caused this error and how to resolve it?
Thanks.

Research direction

Start by reviewing the attached outlog, errlog, and toolkits files alongside the -pc_amgx_amg_method CLASSICAL setting. Trace where the PMIS selector is expected to be registered in the AmgX/PETSc integration and verify the configuration that produces the exception; done means identifying a reproducible cause and a documented resolution.
